since you know 3,4,5 is a pythagorean triple, so is any multiple of those numbers. Looks like 33,44,55 to me.

#2

just multiply 3,4,5 by 4.

#3.

since the diagonal of a 90' square is 90√2, pick the only answer greater than 90. (you might also check it to be sure it fits)

#4.

at 9:00 you have a right triangle with legs 1.2 and 1.5. just figure the hypotenuse. (looks like another 3,4,5 triangle to me!)

#5.

to avoid working with big numbers, scale down by a factor of 6. Now you have a side of 6 and a hypotenuse of 7.

49-36 = 13, so 6*√13 = 21.6
